Toxic effect of tobacco cigarettes, assault, subs encntr

This code describes the toxic effects resulting from exposure to tobacco cigarettes, specifically when the exposure was due to an assault. It indicates that the patient is receiving follow-up care for the initial injury or condition caused by this toxic exposure.

This code is appropriate for subsequent encounters where a patient is being treated for ongoing health issues, complications, or recovery related to a prior assault involving toxic exposure to tobacco cigarettes. Examples include follow-up appointments for respiratory distress, nicotine poisoning symptoms, or other systemic effects after the acute phase of the assault.

• Ensure documentation clearly states the toxic effect is due to tobacco cigarettes and the exposure was an assault.
• Confirm this is a subsequent encounter, meaning the patient is receiving care after the initial treatment for the acute event.
• Always code the specific toxic effect (e.g., acute bronchitis, nicotine poisoning) as the primary diagnosis, with this code as a secondary code to indicate the external cause and encounter type.
